Divide dough in half. Roll each half to a 1/8-inch thickness. Cut eight 5-inch squares out of the dough. Place an apple half on each square. Sprinkle each with 1-tablespoon of the sugar-spice mixture. Moisten edges of dough and bring corners up over apples, pressing edges together. Place covered apples in the prepared baking pan with joined edges either on top or underneath the apples.

Mix together brown sugar, butter, salt, and water; bring to a boil. Pour over dumplings in pan.

Bake at 375 degrees for 45 to 50 minutes, or until apples tenderize. Serve warm.
